@nhoyle, this might be a project that a college student might have the time to take on as a project -- getting some hands-on experience before hitting the workforce. Is there a college or university in your area, where you can bug an IT student to do this?
I work in IT (not as a programmer, though), and no one I know in the field has the time to take on fun projects, cause the paid work is too demanding. Cobbler's Kids, and all that.
Specifically, does anyone have knowledge in making add-ons for firefox? The reason I ask, is that I was recently thinking that sparkpeople's message boards would be vastly improved if an add on that was similar to Reddit Enhancement Suite was made for it.
